RUBBER HEEL non snons.

Application filed Ma 12, 1926,'S.eria1 No. 108,670, and in GermanyFebruary 27, 1928.

My invention relates to rubber heels for shoes, and a purpose of myinvention 1s theprovision of an extremely simple and ineX- pensivedevice capable of being readily applied to the heels of shoes by which arelatively thin and inexpensive layer of rubber can be secured to theheel to function as a rubber heel and which is easily detached from theshoe when worn to permit substi tution of a new layer of rubber or theinter changing of the layer with that of the other shoe. I

I will describeonly one form'ot rubber heel embodyingmy invention, andwill then point out the novel features thereof in claims. p 5 i In theaccompanying drawings,

Figure 1 is a view showing in bottom plan and with a portion thereofbroken away one tour as the shoe heel H and constructed of metal orother suitable inelastic material so as to coiistitutea relatively thinlayer in its association with the shoeheel.

H by screws 1501' other suitablefastening members, and it is provided onthat side coi1-' frontin the heel H with a pair 01' channels 16 whidhextend inwardly from the forward edge of the plate and in convergingrelation to each other. The channels terminate in spaced relation to therear edge of the plate and, hence, their rear ends are closed but theirforward ends are open, even with the plate in attached position to theshoe heel, to permitthe insertion into the channels of a fasteningmember indicated generally at F.

Constituting the bottom layer of the shoe heel is a relatively thinlayer'R of rubber or other suitable elastic material which is adapted tobe detachably secured to the attaching plate A, its elasticityproducing-in its association with the shoe heel the efiect of a rubberheel. This plate R has partly embedded therein a plurality of studs 17This attaching plate is permanently secured tothe heel having relativelylarge heads 18. Thestuds extend upwardly through suitable openings 5 .19formed in the bottom wall ot'the chanirecessed portions 16 'of thechannels. With the studsin this position, the rubber layer can befixedly secured to the attaching plate through the application of thefastening member F. This member comprises a single length of resilientwire bent substantially in the form of a U to provide convergingportions 20 connected at one end by an interme to provide resilientfastening portions 22 'F, the portions 20 are extended into the channels16 to the position shown in Figure 3, wherein the arcuate portions 22move into engagement with the studs 17 at points heneath the heads18,and because of the resiliency of the portions 22 they tend to hold thearc-uate portionsin engagement with the studs so as to preventaccidental removal of the fastening member from the channels, and

further to hold the stud heads '18'against' downward movement throughthe openings 19 so that the rubber heel R is firmly secured in.contiguous relation to the attaching plate of the fastening memberF; Themember F I can be removed by pulling outwardly upon the exposed portion21, thus releasing the studs 17 so that they may be withdrawn throughthe openings 19 in the removal of the rubber heel'from the attachingplate. Where the rubber layers become worn in the usual manner in a pairof shoes, my in fications may be made therein without departing from thespirit of the invention and the spirit and scope of the appended claims.

I claim as my invention:

1. A heel for shoes comprising a'plate having open ended channelstherein and openings communicating with the channels, a second plate,headed studs on the second alate extending through the opening of thefirst plate and into the channels, and a fastening member constructedfrom a single length of wire bent substantiallyin the form of a U havingportions inserted into the channels, a portion connecting said portionsand disposed exteriorly of the plates, and resilient portions on saidportions engaging the shanks of the studs beneath their heads to therebydetachably secure the first plate to the second plate.

2. A heel for shoes comprising a plate adapted to be permanently securedto the heel portion of a shoe and having its upper surface provided witha pair of longitudinally extending channels, the forward ends of whichare open and the rear ends closed, the lower surface of the plate havinga plurality of openings communicating with the channels, a second platehaving headed studs projecting upwardly therefrom and extending throughsaid openings to dispose their heads and a portion of their shanks insaid channels, and a fastening member of substantially U form havingresilient portions recessed at interval-s along their lengths to provideshank engaging portions. said member inserted into said channels betweenthe heads of the studs and bottom walls of the channels so as to causeflexing of the re-silient portions and the seating of the stud shanks insaid recessed portions, to thereby detachaloly secure the first plate tothe second plate.

3. A heel for shoes con'iprising 'a plate adapted to be permanentlysecured to a shoe heel and having its upper surface provided with a pairof longitudinally extending channels converging rearwardly with theirforward ends open and rear ends closed, the lower surface of the platehaving a plurality of openings communicating with the channels, a secondplate, headed studs on the second plate projectin from its upper surfaceand freely extending through said openings to dispose their heads and aportion of their shanks in said channels, and a fastening membercomprising a length of resilient Wire bent substantially in the form ofa U to provide converging portions connected at one end by a transverseportion, and bent upon themselves at the other end to provide resilientfastening portions having arcuate shank engaging portions, the fasteningmember being inserted into the channels between the heads of the studsand bottom walls of the channels so that the arcuate portionsreceive theshank-s of the studs to thereby'detachably secure the first plate to thesecond plate.

4:. A heel forshoes comprising a plate having channels therein andopenings communicating with the channels, a second plate, headed studson the second plate extending through the'openings of the first plateand into the channels, and a fastening member of substantially U formhaving rcsilicnt portions inserted into the channels beneath the headsof the studs so as to engage the shanks of the latter, and a portionconnecting the resilient portions disposed exteriorly of the plates andadapted to be gripped in applying and removing the member, saidresilient portions flexed under engagernent with theshanks of the studs,to thereby detachably secure the second plate to the first plate.

5. A heel for shoes comprising a plate having channels therein andopenings communicating with the channels, a second plate, headed studson the second plate ere tending throughthe openings of the first plateand into the channels, and a fastening member having resilientlyconnected portions inserted into the channels beneath the heads of thestuds and engaging the shanks of the latter, the resilient portionsbeing 'fiBXGCl under their engagement with the studs, to therebydetachably secure the first plate to the second plate.
